SPECIFICATION forming part of Letters Patent N o. 591,766, dated October 12, 1897. Application filed January 28,1897. Serial No. 621,068` (No model.)

To @ZZ whom t may concern:

Be it known that We, EDWARD (1J UDD and HARRY E. CILLEY, residing at Boston, in the county of Suffolk, and ABNER O. PAUL, residing at Lynn, in the county of Essex, State of Massachusetts, citizens of the United States, have invented new and useful Improvements in Sole-Leveling Machines, of which the following is a specification.

This invention relates to the sole-leveling machine for which Letters Patent No. 563,666 were issued July 7, 1896, to Messrs. Judd d: Oilley.

The chief ob jects of the present invention, concisely stated, are to simplify and render the machine more efficient in operation and susceptible of more general use in leveling the soles of boots or shoes; to provide novel means for varying the relative motions of the jack and the shank-rolls; to provide novel means for supporting and adjusting the angies of inclination of the parts orsections composing` the shank and fore-part rolls; to provide means whereby the toe and heel posts of the jack are adjustable laterally and longitudinally to secure correct action and uniform pressure of the leveling-rolls on soles which vary in size or shape; to avoid tipping of the leveling-rolls and thus secure uniform pressure of the same upon soles which vary more or less. in contour, and to provide novel, simple, and eflicient means for correctly adj usting and centering the lasted shoes with relation to the jack and rolls of a sole-leveling machine, whereby the pressure and action of the rolls will be substantially uniform on all soles presented to the saine, and the sole can be adjusted longitudinally and laterally entirely independent of the jack-frame for the purpose of presenting approximately equal surfaces at opposite sides of the median line of the sole to the action of the leveling-rolls.

To accomplish all these objects, our invention involves the features of construction, the combinations or arrangements of parts, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a vertical sectional view taken longitudinally through the center of a soleleveling machine constructed in accordance with our invention. elevation showing the gear connections between the main driving-shaft and the shaft by which' the jack is rocked longitudinally.

Fig. 14: is a detail view, on a reduced scale, showing the fore-part rolls and their supporting devices. Fig. 15 is a detail sectional View taken on the line 15 15, Fig. 1, to more clearly show the connection between the eccentric strap or rod and the rocking jack. Figs. 16, 17, and 18 are diagrammatical views indicating different positions of the shoe-last obtained by adjusting the last-pin according to our invention. Figs. 19 and 2O are detail views of modifications, hereinafter fully explained.

In order to enable those skilled in the art to make and use our invention, We will now describe the same in detail, referring to thev drawings, wherein- The numeral 1 indicates the main frame, which may be of any construction suitable for the purpose in hand. The lower portion of the main frame is provided with suitable bearings, in Which is arranged a horizontal main driving-shaft 2, having at one end a pinion 3, Figs. 2 and 3, meshing into a comparatively large spur gear-wheel 4, journaled to rotate upon a iixed stud 5, Fig. 3, projecting Fig. 2 is a detail side from the main frame. The spur gear-wheel 4 is provided'at its inner side with a rigidlyattached pinion (5, meshing into a spur gearwheel 7 secured to one end of a shaft 8 and of substantially the same diameter as the spur gear-wheel 4, the construction being such that the required rotary motion is transmitted to the shaft 8 from the main driving-shaft 2. The shaft 8 is provided with an eccentric 9, Fig. 1, with which engages one end of an eccentric strap or rod 10, pivoted at its other end through the medium of a horizontal pin 12 to a clamp 13, which is forked to provide a dovetail groove or way 14, engaging and slidable upon a dovetailed arm 15, secured or formed with the rocking jack-frame 16 and preferably arc-shaped, as shown in Fig. 1.

The forked clamp 13 is adjustable to differen-t positions upon the arcshaped arm 15 and is-held in a fixed position with relation to this arm after adj ust-ment through the medium of a clamping-screw 17, which is carried by the clamp and is adapted to bear against the arcshaped arm. The frame of the jack is mounted upon a jack-supporting shaft 18, and the v rotary motion of the shaft 8 through the medium of the eccentric strap or rod 10, imparts a longitudinal rocking motion to the jackframe, as will be obvious. The extent of motion or throw of the jack-frame can be accurately and nicely regulated or varied by adjusting the forked clamp 13 upon .the arcshaped arm 15.

Instead of making the arm 15 arc-shaped or segmental, as shown in Fig. 1, we may provide the jack-frame with a rectilinear arm 15?, as shown in the modified construction, Fig. 19. The rectilinear arm 15a is dovetailed thesarne as the arm 15, and the forked clamp 13pivoted to the strap or rod 10 by pivot-pin 12, is adjustable on the arm 15, substantially the same as described with reference to the adjustment of the fixed clamp on the arcshaped arm 15.

The yoke-shaped frame 1Q, on which the fore-part leveling-roll 2O is mounted, as will. hereinafter appear, is pivoted at its rear end tothe top portion of the main frame 1 and is connected by a'rod 21 with the treadle-frame 22, as in the former patent, so that the yokeshaped frame can be forced downward. The carrier-frame 23 of the fore-part leveling-roll is connected by a rod 24 with one arm of a bell-crank lever 25, the other arm of which is connected by a rod 26 with an eccentric on the main driving-shaft 2, which latter is provided with a belt-pulley 27, by which; it can be' rotated by suitable power, as in the former patent. The yoke-shaped frame 28,x onwhich the shank-roll 29 is mounted, as will hereinafter appear, is adjustably conne'ctedwith a main yoke-shaped frame 28a, substantially as shown and described in the patent before mentioned. The frame 28 is connected with one arm of a bell-cranklever 30, the same as in the former patent, and the other arm of this bell-crank lever is connected by a rod 31 with an eccentric on the main driving-shaft 2. The bell-crank lever 30 is pivotally mounted in the upper end of a rocker-frame 32,4 supported by a shaft 33. The rocker-frame 32 is provided With a dovetailed arm 34, preferably arc-shaped and of substantially the same construction or form as the dovetailed arm 15.

v This arm 34 is provided with a forked clamp 35, pivoted to one end of an eccentric strap or rod 36, engaging an eccentric 37 on the jack-operating shaft 8. The forked clamp 35 is adjustable on the arc-shaped arm 34 and is held in any position of adjustment through the medium of a clamping-screw 38 in substantially the same manner as the forked clamp 13 is adjustably held upon the arcshaped arrn 15 of the jack. The eccentric 37 serves to raise and lower the eccentric strap or rod 3G, whereby the rocker-frame 32 is oscillated or rocked. The rocking motion of the rocker-frame 32 is imparted to the bellcrank lever 30, and since the latter is oscillated or vibrated on the rocker-frame through the medium of the rod 31, actuated by the main driving-shaft, it will be obvious that a longitudinal traversing motion is imparted to the yoke-shaped frame 28 and the shank-roll', while at the same time this yoke-shaped frame and the shank-roll will be vibrated longitudinally by themovements of the bell-crank lever 30. The extent of motion or throw of the rocker-frame 32, and consequently the extent of the longitudinal traversing motion of the frame 28 and the shank-roll, is susceptible of being conveniently and quickly regulated or varied by simply adjusting the forked clamp 35 on the arc-shaped frame 34. The adj-ustm-ent of the forked clamp in one direction lengthens the throvT of the rocker-frame, and, conversely, the adjustment of the forked vclamp in the opposite direction shortens the throw of the rocker-frame, as will be obvious without further explanation. The connections described and shown between thel jackoperating shaft 8 and the jack-frame 16 and rocker-frame 32 provide very simplified means for regulating and varying the throw of the jack and the traversing motion of the shankroll, whereby the relative positions of the jack and shank-roll can be altered at will and the latter can be made to pass up onto the toe of the sole, or back onto the heel portion thereof, a greater or less distance, as circumstances may require.

Instead of making the arm 34 arc-shaped or segmental, as shown in Fig. 1, We may provide a rectilinear arm 34n on the rocker-frame 32, as shown in the modification, Fig. 20. Theforked clamp 35, pivotally connected with the strap or rod 36, is adjustable on the rectilinear arm 34, the same as described with reference to the adjustment of the forked clamp on the arc-shaped arm 34.

IIO

The yoke-shaped frame 28a is connected by a rod 39 with the tread'le-frame 22 for the purposeof forcing said frame and the shankroll downward, as usual. The treadle-frame 22, the oounterbalance-weight 40, and the connections between the treadle-frame and the weight are preferably constructed the same as disclosed in the former patent, but any suitable treadle mechanism may be employed.

The jack-frame 16 is provided with a laterally-movable frame 4l, preferably composed of two angularly-arranged shoe-supporting arms 42 and 43, Fig. l, constructed, arranged, and pivotally mounted substantially the same as in the former patent, and each designed to carry toe and heel posts and a toe-guard, as hereinafter explained, but as regards this part of our invention a single shoe-supporting arm may be employed.Y We prefer, however, to use the two angularly-arranged arms in that while one arm supports a boot or shoe under the leveling-rolls the other arm is in a position to enable a boot or shoe to be placed thereupon in readiness to be moved into position under the leveling-rolls at the proper time. lnasmuch as both arms and the heel and toe posts and other parts carried thereby are of like construction we will merely describe the parts belonging to one of the arms, as this is sufficient to enable this part of the invention to be clearly understood. The arm-as, for example, the arm 42-is constructed or provided on its upper side with a horizontal dovetail guide or way 44, engaging a dovetail groove 45, provided longitudinally in a slide-block 46, Figs. 4 and 5, having on its upper side a dovetail guide or way 47 extending transversely with respect to the arm 42. The dovetail guide or way 47 engages a dovetail groove 48, formed in the base-plate 49 of a heel-post standard 50. The slideblock 46 is adjustable longitudinally of the shoe-supporting arm 42, and is held rigid in a fixed position after adjustment through the medium of a clamping-screw 5l, carried by the slide-block and adapted to bear at its inner end against the dovetail guide or way 44.

The base-plate 49, carrying` the heel-post standard 50, is adjustable in engagement with the dovetail guide or way 47 in a direction transversely of the shoe-supporting arm 42, or, rather, in a direction at right angles to the direction in which the slide-block 46 is adjustable. The base -plate 49 is held rigid after adjustment through the medium of a clamping-screw 52, carried by the base-plate and bearing at its inner end against the dovetail guide or way 47, the same as described with reference to the clamping-screw 5l. The lower portion of the heel-post standard 50 is externally screw-threaded, as at 53, to engage an internally-screw-threaded sleeve 54, having a suitable handle 55, by which it may be turned upon the standard and be thereby raised or lowered. stru cted at its upper end portion with a spiral incline, as at 56, which bears against the base or lower end of a quick-pitch screw-thread 57 provided upon a sleeve 58, fitting the stan dard 50. A locking-plate 59, secured by The sleeve 54 is conscrews to the sleeve 54, laps over the quickpitch screw-thread 57 and holds the sleeve 58 in operative connection with the sleeve 54. The face of the locking-plate 59, which engages the quick-pitch screw-thread, should be properly beveled to fit the thread and permit the necessary motion of the sleeve 54, the construction being such that when the handle 55 is operated to turn the sleeve 54 the locking-plate 59, acting upon the quick-pitch screw-thread 57, causes the sleevey 58 to be lowered when the sleeve 54 is turned in one direction and to be raised when said sleeve is turned in the, opposite direction by means of the spiral incline 56. The upper end of the standard 50 is provided with a transverse pin 60, which serves as a pivot for a last-pin holder 61, preferably forked to receive the base or block 62 of the last-pin 63. The base or block 62 of the last-pin is held between the arms or members of the forked holder Gl'by means of a clamp-screw 64.V 'This clampingscrew is arranged longitudinally or at right angles to the pivot-pin 60, and the last-pin 63 is susceptible of being oscillated or rocked laterally to any required position, after which it can be securely held in position by tightenin g the clamping-bolt. The last-pin holder 6l is susceptible of rockingvor tipping longitudinally, and is pivotally connected by a link 65 with the upper end of the sleeve 58 in such manner that when this sleeve is raised or lowered by operating the handle 55, as before explained, the last-pin holder 6l Will be swung longitudinally on or with the pivot-pin 60.

The longitudinally and laterally adjustable last-pin enables the boot or shoe to be accurately adjusted and centered, in the manner and for the purposes more fully hereinafter explained.

In the modified construction, Figs..6 and 7, the last-pin 63a is provided with a bifurcated base or lower end 62', arranged upon a clamping-screw 64, passing through a lastpin holder 6l, mounted on the upper end of the heel-post standard 50 through the medium of a transverse pivot-pin The lastpin holder 6 lfL is pivotally connected by a link 65n with a sleeve 58, constructed and operated in the same manner as described with reference to the sleeve 58, Figs. 4 and 5. The clamping-screw 64a passes through the transverse pivot-pin 60 for the purpose of placing the pivot of the last-pin as near as possible to the last where the latter rests upon the base of the last-pin, so that when the last is jacked, as hereinafter explained, it will not be moved bodily forward an undue extent, but will be tipped upon or with the pivot-pin 60a.

The toe-post standard 66 is provided in its base portion with a transverse dovetail groove 67, engaging a transverse dovetail guide or way 68, formed on the upper side of the slideblock 69, which ismovable longitudinally on the dovetail guide or Way 44 of the shoe-sup,

The slide-block 69 is pro- A porting arm 42.

vided with a clamping-screw 70, bearing at its inner end against the dovetail guide or way 44: for the purpose of rigidly holding the slide-block in any position to which adj usted. The lower portion of the standard 66 is also provided with a clampingscrew 71, bearing at its inner end against the transverse guide or way 68, whereby it is possible to adjust the standardv laterally and rigidly lock it in position after the desired adjustment is effected. The toe-post standard is constructed with a vertical cylindrical bore 72, in which is arranged a screw-threaded shank 7 3, having a head 74 at its upper end. This head contains a recess or socket in which is arranged a toe-rest 75, preferably supported by a transverse pin 76, secured to the head 74 of the screw-threaded shank. The upper end of the standard 66 is provided with a rotatable hand-nut 77, engaging the screw-threaded shank 7 3, which latter is provided with a cross-pin 7 8, which prevents it from turningwhen the hand-nut is rotated to raise or lower the shank. The standard 66 is provided with a hub 79, on which a spur-gear 8O is adapted to rotate. This spur-gear engages a pinion S1, having a central screw-threaded orifice engaging the vertical screw-threaded shank 82 of the toe-guard S3. The smooth part of the shank of the toe-guard passes through a socket 84, forming a part of the head 74E, and the toe-guard is provided with a pendent stem 85, engaging an orifice 86 in the head 7-l for the purpose of preventing the toeguard and its shank from turning. The pinion 81 is rotatably held upon the base portion of the standard 66 through the medium of a locking-plate 87, secured in position by suitable screws or otherwise. The pinion S1 is-rotated by manually rotating the spur-gear SO, and by this means the toe-guard 83 can be accurately and nicely adjusted with relation to the toe portion of the sole being leveled. The lower end of the screw-threaded shank S2 is guided by a socket SS, to` which the lockingplate S7 is secured. By the construction and arrangement of parts described and shown the toe-post is susceptible of being accurately and nicely adjusted longitudinally and laterally in amanner similar to or the same as the heel-post.

If the handle 55 of the heel-post be turned in the proper direction, the sleeves 54C and 58 will be raisedv and the last-pin holder 61 will be tipped forward for the purpose of forcing the toe of the shoe down upon the toe-rest 75.

In the operation of a sole-leveling machine such as disclosed in the patent before mentioned when soles of certain contour are operated upon the fore-part roll tends to tip the boot or shoe and force it out of the toe-rest, and the roll also unevenlyT presses upon 'opposite sides of the sole. This is avoided by our present invention, as We will now proceed to explain in detail. In Fig. 16 a last is indicated by full linesmounted upon the lastpin 63, the pin-hole of the last being drilled straight therei'nor at right angles to the surface which bears upon the last-pin holder. The surface of the fore part of the shoe-sole (indicated in Fig. 16) extends at an angle in such mann er that the right-hand side is measurably higher than the left-hand side. If a shoe of this contour is placed in an ordinary sole-leveling machine, the leveling-rolls tend to tip and force the shoe out of the toe-rest, while at the same time. an uneven pressure Ais placed upon opposite sides of the sole. To

counteract this, the last-pin of our improved machine is tipped laterally to the position indic-ated by dotted lines, Fig. 16, whereby the surface of the fore part of the sole is made substantially level and the two sides of the sole are at about the same height, so that the leveling-roll-will bear evenly and uniformly upon the entire surface of the fore part. This adjustment of the last-pin 63 is effected by shifting or swinging the pin laterally and `then clampingit in its adjusted position through the medium of the clamping-screw 64, Figs. 4 and 5, which prevents the pin from turning very easily, but at the same time enables the angle of inclination to be varied by the operator tipping the last to the required position, while the shoe is not jacked and firmly held against the toe-rest 75. When the boot or shoe is jacked by tilting the lastpin longitudinally, the last-pin is locked firmly in position asvregards lateral motion by frictional contact between the base of the last-pin and the last-pin holder 61. By this means the last-pin can be conveniently ad justed laterally while the shoe is unjacked, but is locked firmly in position against lateral motion when jacked and subjected to the action of the levelng-rolls- In Fig. 17 the pin-hole in the last is represented as drilled crooked or at an acute angle to the part of the last which rests against the last-pin holder. This figure indicates by full lines the postion first assumed by the last when placed upon the last pin and by dotted lines the position to which it is adjusted by tipping the last-pin laterally to place the sole approximatelylevel, where by an even uniform pressure will be exerted thereupon by the leveling-rolls. Y

In Fig. 18 isindicated the mannerin which a boot or shoe is adjusted and centered through the medium of the lateral adjustment of the toe and heelposts. This figure indicates by full lines the position assumed by the boot or shoe when placed in the machine with the heel and toe posts centrally thereof. The line a b indicates the center line of the machine, and the parts marked with the reference-letters c and CZ indicate the toerests and the last-pin, respectively. A comparison of the outline of the boot or shoe sole indicated by full lines with the center line ab shows that one side of the sole is much nearer the center line than the other side, in consequence of which the leveling-rolls will not bear evenly and uniformly upon the surface IIO of the sole, so that the best results are not obtained. To avoid this objection and to accurately and correctly adjust and center the shoe, the toe and heel posts are laterally adjusted in the manner hereinbefore described, whereby it is possible to shift the shoe from the position represented in full lines to the position indicated by dotted lines in Fig. 18. By this adjustment the two longitudinal side portions of the sole are made approximately equal at opposite sides of the center line ab, and consequently the action and pressure of the leveling-rolls will be even and uniform.

In our invention the lasted boot or shoe can be adjusted longitudinally and laterally entirely independent of the rocking or longitudinally movable jack-frame 16. In the practical operation of the machine it is possible to independently adjust the toe and heel posts longitudinally and laterally, which is important in that sometimes it is essential to secure the desired results to adjust the heel-post a greater distance than the toepost or to move the heel-post laterally in one direction and the toe-post laterally in the opposite direction. All these adjustments can be conveniently and quickly effected by our invention, and the adjustments of the heel and toe posts can, if desired, be accomplished while the jacket frame or jacket proper remains motionless.

As best seen in Fig. 10, the shank-leveling roll 29 is made in two parts or sections somewhat conical in form or shape and mounted to turn or rotate upon studs fixed to the lower ends of the arc-shaped or segmental plates 90, 4having segmental slots 91. The front portion of the yoke-shaped frame 28 is provided with a head 92u, having a pendent arm or hanger 92, carrying at the lower end a pivot-pin 93, and on this pivot-pin, between the head 92 and the pendent arm or hanger 92, is pivotally mounted a vertical plate 94, preferably of the segmental outline clearly shown in Fig. 12. This plate is mounted on the pivot-pin 93 through the medium of an eye or socket 95, formed centrally of the plate, so that the latter can rock laterally. The top portion of the plate is provided with a pin-hole 96, adapted to receive a springpressed pin 97, movable horizontally in the pendent arm or hanger 92 and having a suitable handle or knob 98 by which it can be drawn outward against the tension of the spring 99 for the purpose of disengaging the pin from the pin-hole, so that it is possible by holding the pin retracted for the plate 94 to freely oscillate or rock laterally. The curved arms of the plate 94 are each provided with two bolt-holes 100 and 101, and the segmentally-slotted plates 91 are arranged vertically on the plate, so that they can be adjustably clamped thereupon through the medium of guide-bolts 102 and clampingbolts 103. The bolts 102 engage the boltholes 101 and the clamping-bolts 103 pass through the segmental slots 91 and screw into the bolt-holes 100, as will be clearly understood by reference to Fig. 13. By unscrewing the clainping-bolts 103 the segmentally-slotted plates 90 can be adjusted in circular paths for the purpose of varying the angles of inclination of the axes of the parts or sections composing the shank-roll, afterl which the segmental plates can be rigidly secured in their position of adjustment by tightening the clamping-bolts, as will .be obvious. By the means described the angle of the parts composing the shank-roll can be conveniently and quickly adjusted according to the conditions required in operating on soles which vary in contour. The plate 94 can be locked rigid to the head 92a and consequently to the yoke-shaped frame 28 by the pin 97, so that the shank-roll is held rigid as regards lateral oscillation, or the shankroll may be left free to tip or tilt laterally during the leveling operation. If the shankroll is to be held rigid, the spring-pin 97 is caused to engage the pin-hole 96, and conversely if it is desired that the shank-roll should be free to tip or tilt laterally the spring-pin 97 is withdrawn and held from engagement with the pin-hole 96, so that the plate 94 and the shank-roll are free to rock laterally.

The shank-roll 29, mounted and adjustable in the manner above described, is susceptible of being raised and lowered for the purpose of varying its height relatively to the jack. This is accomplished by providing the head 92a witha swiveled screw-shaft104, Fig. 11, engaging a screw-thread socket 105, projecting upward from the front end of the frame 28 in such manner that by turning the screw-shaft 104 in one direction the head 92a and shank-roll 29 will be raised and by turning the screw-shaft in the opposite direction the head and shank-roll will be lowered. The screw-shaft 104 may be turned in any suitable manner, but I prefer to construct its upper end with an angular head 106 to receive a wrench, by which the shaft can be conveniently and quickly rotated in either direction.

As best seen in Fig. 14, the fore-part-leveling roll 20 is made in two parts or sections somewhat conoidal in shape and mounted to turn or rotate upon studs fixed to the lower ends 107 of two segmental or' arc-shaped plates 10S, having segmental slots 109. These IOO IIO

segmental plates are mounted upon a support 110, similar to plate 94, Fig. 12, having avertical front face and pivotally mounted at its lower end on a stud-bolt 114 upon the carrierframe 23, which is pivotally mounted ina yoke-shaped frame 19. The segmental plates 108 are each secured in position through Vthe medium of a guide-bolt 112 and a clamp-bolt 113, the same as the bolts 102 and 103, Figs. l0 and 13, whereby the segmental plates can be adjusted in circular paths and subsequently be rigidly locked in fixed positions by tightening the clamping-bolts 113 and 112. By this means the axes of the two parts or sections of the fore-part-leveling roll can be made to stand at varying angles of inclina-4 tion relative to each other, whereby the roll is susceptible of adjustment to correctly operate upon the shoe-soles,which widely vary in contour. The support 110, like plate 94, is pivotally mounted at its lower end on a studbolt 114 andis provided with a spring-pressed pin 115, by which it can be locked to or released from the carrier-frame 23, substantially as described with reference to the plate 94, Figs. 10, 1l, and 12.

By the use of the terms or words lateral and longitudinal in the foregoing description it is to be understood that the word longitudinal is used with reference tothe length of the machine-that is to say, the direction of the length of the shoe as the sole is being leveled-and the word lateral is used with reference to the sides of the machine-that is to say, the sides of the shoe as the sole is being leveled--as is Well understood in this art.

The present invention materially simplifies the construction and operation of the machine and renders it susceptible of more general application for leveling boot or shoe soles which Widely differ in contour or size.

Having thus described our invention, what we claim is'-'- l. The combination of a rocking jack having an arc-shaped or segmental arm, a leveling-roll, a rocker-frame connected with the leveling-roll, an arc-shaped or segmental arm by which the rocker-frame is rocked,a jack-operating shaft having eccentrics, rods engaged at one end with the eccentrics, clamps pivoted to the other ends of the rods and adjustable in circular paths in engagement with the arc-shaped or segmental arms, and clamping devices for rigidly securing the forked clamps to said arms in different positions of adjustment, substantially as described.
